Electron (oz6468)

About this Plan

Electron. Radio control cabin model for single channel. From the article: 'Fly em by Radio'.

Quote: "Build and fly 'Electron' with a single-channel radio receiver approved for operation without a license. Fly 'Em By RADIO, by William Winter.

FLECTRON is one of several experimental models designed especially to utilize all the structural and design features necessary for reliable radio control of a model plane having a wing loading of about 13 oz per sq ft of wing area when fitted with radio and batteries. High air speeds have been sacrificed deliberately in order to obtain stability and versatility in flight, characteristics which are essential to successful radio control of a model plane.

Rudder-only control gives satisfactory maneuverability in flight as the plane can be fast-dived, zoomed, stalled and even looped if the speed build-up is sufficient. Of course, accurate approaches and landings, take-offs, lazy eight, Immelmanns and other more intricate flight maneuvers require skill and experience on the part of the operator.

The radio-control unit employs a single-channel receiver with a sensitive relay that closes a circuit to operate an escapement which is rubber-strand driven and is connected to the rudder by a music-wire linkage. This arrangement permits use of left and right rudder positions and neutral position for straight flight. Of course, it is possible to develop radio control from the single-channel receiver to include as many as six po-sitions for rudder and elevator, as well as throttle and wheel-brake control, but in this case these details have been left to the builder.

As pictured, Electron is powered with a spark-ignition engine of .24 cu in displacement, but experiment has shown that the plane flies well when fitted with engines ranging from .19 to .29 displacement. If other engines are used, some experimentation with the throttle setting will be necessary.

Fuselage: The fuse-lage is of the familiar box construction. The side frames are built first, then joined by top and bottom crosspieces..."

Update 26/03/2015: Added supplement plan (scaled up to full-size, usable) thanks to aeromeddler.

Update 04/04/2015: Replaced this plan (again) with a clearer copy, thanks to rescan by dfritzke, cleanup and scaling by aeromeddler.

Quote: "Hi Steve, Yes much better scan. Have ignored the one inch squares and as the plan has so many measurements I have used these. I basically cut the plan up into its component parts. All measurements in all directions should now be nearly correct as makes no difference."
